A Healthcare Project is constructing a new building adjacent to an existing LEED Certified hospital facility. The new building's location is on the same hospital campus as the certified facility. The entire hospital campus was analyzed with an Environmental Site Assessment (ESA) as part of the certified facility's project scope. The new building project needs to complete a new Phase I ESA if
Correct Answer: D
Explanation the local equivalent standard is more stringent than ASTM E1527-05 According to the LEED v4 Reference Guide for Building Design and Construction, a Phase I ESA is required for all projects, except for those located on previously developed land that has not been used for industrial, commercial, or agricultural purposes. The Phase I ESA must follow the ASTM E1527-05 standard or a local equivalent. However, if the local equivalent is more stringent than the ASTM standard, then the project must comply with the local equivalent. Therefore, if the new building project is located in a jurisdiction that has a more rigorous standard for Phase I ESA than ASTM E1527-05, then it must complete a new Phase I ESA, regardless of the previous ESA done for the certified facility.

Question 102
What credit rewards customers who change their normal consumption patterns in response to the varying price of energy over time?
Correct Answer: A
The Energy and Atmosphere Credit, Demand Response rewards projects that participate in demand response programs that aim to reduce peak electricity demand and shift the load to off-peak periods. The LEED v4 Reference Guide for Building Design and Construction states that "the intent of this credit is to increase participation in demand response technologies and programs that make energy generation and distribution systems more efficient, increase grid reliability, and reduce greenhouse gas emissions"1. The project team must either implement a permanent demand response program or develop a plan to implement a program within a year of occupancy. The project team must also demonstrate that the building has the capability to reduce its peak electricity demand by at least 10% in response to demand response signals.

Question 103
Which of the following is the location of CO2 sensors in naturally ventilated spaces to comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance?
Correct Answer: C
Explanation According to the LEED v4: Building Design + Construction Guide, the location of CO2 sensors in naturally ventilated spaces to comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance is between 3 ft. and 6 ft. (1 m and 2 m) above the floor. This is one of the requirements for Option 2. Naturally Ventilated Spaces, which applies to projects that rely on natural ventilation for all or part of the occupied spaces.The CO2 sensors must be located in each zone with natural ventilation openings, and must be capable of generating an alarm when the CO2 concentration exceeds the design value1. The other choices are not correct, because: * At least 6 ft.(2 m) above the floor is the location of CO2 sensors in mechanically ventilated spaces, not naturally ventilated spaces1. * At least 3 ft.(1 m) away from windows is a general guideline for locating CO2 sensors, but it does not specify the height above the floor2. * On the ceiling 3 ft.(1 m) away from adjacent walls is not a recommended location for CO2 sensors, as it may not reflect the actual CO2 concentration at the breathing zone of the occupants2.

Question 104
What issue must be present on the project site to achieve Location and Transportation Credit, High-Priority Site, Option 3. Brownfield Remediation?
Correct Answer: B
Detailed Explanation: For the Brownfield Remediation option under the High-Priority Site credit, the project site must include contaminated soil or groundwater requiring cleanup to improve environmental conditions. This credit incentivizes the redevelopment of previously unusable or hazardous sites, helping to promote environmental restoration and sustainable land use.
Question 105
Which of the following must be included in the Sustainable Sites Credit, Site Assessment?
Correct Answer: C
Explanation The correct answer is C. Proximity of vulnerable populations to major sources of air pollution. According to the LEED v4.1 Reference Guide for Building Design and Construction, the Site Assessment credit requires projects to conduct and document a site inventory and analysis that covers the following topics1: Topography Hydrology Climate Vegetation Soils Human use Human health effects The human health effects topic includes identifying the proximity of vulnerable populations, such as children, elderly, or low-income residents, to major sources of air pollution, such as highways, power plants, or industrial facilities. This information can help the project team design strategies to minimize the exposure of occupants and visitors to harmful pollutants and improve the indoor and outdoor air quality of the project1. The other options are not required for the Site Assessment credit, although they may be relevant for other credits or prerequisites. A targeted Brownfield remedy plan is required for the Brownfields Remediation credit, which applies to projects located on sites contaminated by past uses1. A historic preservation plan to include neighboring properties is not required for any LEED credit, although projects that involve historic buildings or districts must comply with local regulations and standards for preservation1. The surrounding density within a 1/4 mi. (0.40 km) radius of the project boundary is not required for the Site Assessment credit, but it is used to calculate the points for the Surrounding Density and Diverse Uses credit, which encourages projects to locate in areas with high levels of existing development and mixed land uses1.
